Which of the following can be accurately determined using Newtonian physics?

A. The speed of an object moving at nearly the speed of light

B. The momentum of a car

C. The position of an electron

D. The length of an object moving at nearly the speed of light

The correct option is B.

Newtonian physics refers to the study of the motion of bodies and the forces acting on them according to the Newton laws of motion. This aspect of physics is also known as classical mechanics. Newton laws of motions deal with the speed of object in motion and those that are at rest. Using Newton laws of motion, the momentum of a car can be easily determined.
